Intermittent Weak A/C Airflow with Bad Odor
The A/C system in your 2020 Honda CR-V is producing weak, intermittent airflow accompanied by a bad smell. This suggests a blockage or contamination in the evaporator or cabin air filter, possibly with mold or debris, rather than a refrigerant issue.
Diagnosis Details
Possible Causes
Clogged or dirty cabin air filter restricting airflow and trapping moisture, leading to mold growth and odor.
Mold or bacterial growth on the evaporator coil due to moisture buildup, causing bad smell and reduced airflow.
Blower motor resistor or fan speed controller failing intermittently, causing weak or no airflow.
